I would like to contribute snapd project. Currently I occasionally look at the issues at Launchpad and send PR after fixing. However, it would be great if we can communicate with the developer team and request for the issues and ask some project structure questions(for example, what is the usage purpose of snap-ctl under the hood, etc?).
I guess Rocketchat and IRC is not actively used for now and discussion forum might not be right place for detailed questions about technical details.
